Systems and methods for directing application updates

ABSTRACT

A computer-implemented method for directing application updates may include (1) identifying information that indicates a rate at which an earlier version of an application is exploited in attacks on computing system security, (2) identifying additional information that indicates a rate at which a later version of the application is exploited in attacks on computing system security, (3) determining how updating the application from the earlier version to the later version will impact computing system security by comparing the rate the earlier version of the application is exploited with the rate at which the later version of the application is exploited, and (4) directing a computing system with a determination about updating an installation of the earlier version of the application to the later version of the application based on determining how updating the application will impact computing system security. Various other methods, systems, and computer-readable media are also disclosed.

BACKGROUND

Consumers and businesses increasingly rely on computing systems (e.g., smartphones, tablets, laptops, etc.) to store and manage sensitive data. Consequently, malicious programmers seem to continuously increase their efforts to gain illegitimate control and access to these computing systems through the use of viruses, Trojan horses, worms, and other programs meant to compromise computing systems and data belonging to other people.

The level to which a computing system is exposed to malicious attacks may be based on the level to which software components (e.g., the operating system and applications) running on the computing system are exposed to malicious attacks. Unfortunately, consumers may be in a poor position to assess the vulnerability of the various software components that run on their computing systems. Some consumers may assume that newer versions of software components are more secure and trustingly accept all software updates, some of which may increase their exposure to attacks. Other consumers may assume that currently installed versions of software components on their computing systems are adequately secure, and fail to take the time or effort to perform software updates that would lower their exposure to attacks. Accordingly, the instant disclosure identifies and addresses a need for additional and improved systems and methods for directing application updates.

SUMMARY

As will be described in greater detail below, the instant disclosure generally relates to systems and methods for directing application updates by determining whether newer versions of applications are exploited more (or less) by attacks and then directing computing systems with instructions that facilitate and/or encourage updates to more secure versions of applications and/or directing computing systems with instructions that prevent, protect against, and/or discourage updates to less secure versions of applications.

In one example, a computer-implemented method for directing application updates may include (1) identifying information that indicates a rate at which installations of an earlier version of an application are exploited in attacks on computing system security, (2) identifying additional information that indicates a rate at which installations of a later version of the application are exploited in attacks on computing system security, (3) determining how updating the application from the earlier version to the later version will impact computing system security at least in part by comparing the rate at which installations of the earlier version of the application are exploited with the rate at which installations of the later version of the application are exploited, and (4) directing at least one computing system with a determination about updating an installation of the earlier version of the application to the later version of the application based at least in part on determining how updating the application will impact computing system security.

In some examples, determining how updating the application from the earlier version to the later version will impact computing system security may include determining that the earlier version of the application is more likely to be exploited than the later version of the application. In these examples, directing the computing system with the determination about updating the installation of the earlier version of the application may include directing the computing system to update the installation of the earlier version of the application to the later version of the application. Additionally or alternatively, in these examples, directing the computing system with the determination about updating the installation of the earlier version of the application may include directing the computing system to display a notification recommending that the installation of the earlier version of the application be updated to the later version of the application. As another alternative in these examples, directing the computing system with the determination about updating the installation of the earlier version of the application may include directing the computing system to disable the installation of the earlier version of the application until the installation is updated to the later version of the application. Additionally or alternatively, directing the computing system with the determination about updating the installation of the earlier version of the application may include sandboxing the installation of the earlier version of the application.

In some examples, determining how updating the application from the earlier version to the later version will impact computing system security may include determining that the earlier version of the application is less likely to be exploited than the later version of the application. In these examples, directing the computing system with the determination about updating the installation of the earlier version of the application may include directing the computing system to not update the installation of the earlier version of the application to the later version of the application. Additionally or alternatively, in these examples, directing the computing system with the determination about updating the installation of the earlier version of the application may include blocking an attempt to update the installation of the earlier version of the application to the later version of the application. As another alternative in these examples, directing the computing system with the determination about updating the installation of the earlier version of the application may include directing the computing system to display a notification recommending that the installation of the earlier version of the application not be updated to the later version of the application.

In some examples, directing the computing system with the determination may be further based on determining that a stability rating of the later version of the application exceeds a predetermined threshold.

In one embodiment, a system for implementing the above-described method may include (1) an identification module that (i) identifies information that indicates a rate at which installations of an earlier version of an application are exploited in attacks on computing system security and (ii) identifies additional information that indicates a rate at which installations of a later version of the application are exploited in attacks on computing system security, (2) a determination module that determines how updating the application from the earlier version to the later version will impact computing system security at least in part by comparing the rate at which installations of the earlier version of the application are exploited with the rate at which installations of the later version of the application are exploited, (3) a direction module that directs at least one computing system with a determination about updating an installation of the earlier version of the application to the later version of the application based at least in part on determining how updating the application will impact computing system security, and (4) at least one processor configured to execute the identification module, the determination module, and the direction module.

In some examples, the above-described method may be encoded as computer-readable instructions on a computer-readable-storage medium. For example, a computer-readable-storage medium may include one or more computer-executable instructions that, when executed by at least one processor of a computing device, may cause the computing device to (1) identify information that indicates a rate at which installations of an earlier version of an application are exploited in attacks on computing system security, (2) identify additional information that indicates a rate at which installations of a later version of the application are exploited in attacks on computing system security, (3) determine how updating the application from the earlier version to the later version will impact computing system security at least in part by comparing the rate at which installations of the earlier version of the application are exploited with the rate at which installations of the later version of the application are exploited, and (4) direct at least one computing system with a determination about updating an installation of the earlier version of the application to the later version of the application based at least in part on determining how updating the application will impact computing system security.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

The present disclosure is generally directed to systems and methods for directing application updates. As will be explained in greater detail below, by determining whether newer versions of applications are exploited more (or less) by attacks and then directing computing systems with instructions that facilitate and/or encourage updates to more secure versions of applications and/or directing computing systems with instructions that prevent, protect against, and/or discourage updates to less secure versions of applications, the systems described herein may enhance the security of computing systems through intelligent application updating.

The following will provide, with reference to FIGS. 1, 2, and 4, detailed descriptions of exemplary systems for directing application updates. Detailed descriptions of corresponding computer-implemented methods will also be provided in connection with FIG. 3. In addition, detailed descriptions of an exemplary computing system and network architecture capable of implementing one or more of the embodiments described herein will be provided in connection with FIGS. 5 and 6, respectively.

FIG. 1 is a block diagram of exemplary system 100 for directing application updates. As illustrated in this figure, exemplary system 100 may include one or more modules 102 for performing one or more tasks. For example, and as will be explained in greater detail below, exemplary system 100 may also include an identification module 104 that may identify information that indicates a rate at which installations of an earlier version of an application are exploited in attacks on computing system security. Identification module 104 may also identify additional information that indicates a rate at which installations of a later version of the application are exploited in attacks on computing system security. Exemplary system 100 may additionally include a determination module 106 that may determine how updating the application from the earlier version to the later version will impact computing system security at least in part by comparing the rate at which installations of the earlier version of the application are exploited with the rate at which installations of the later version of the application are exploited.

Exemplary system 100 may also include a direction module 108 that may direct at least one computing system with a determination about updating an installation of the earlier version of the application to the later version of the application based at least in part on determining how updating the application will impact computing system security. Although illustrated as separate elements, one or more of modules 102 in FIG. 1 may represent portions of a single module or application.

In certain embodiments, one or more of modules 102 in FIG. 1 may represent one or more software applications or programs that, when executed by a computing device, may cause the computing device to perform one or more tasks. For example, and as will be described in greater detail below, one or more of modules 102 may represent software modules stored and configured to run on one or more computing devices, such as the devices illustrated in FIG. 2 (e.g., computing device 202 and/or server 206), computing system 510 in FIG. 5, and/or portions of exemplary network architecture 600 in FIG. 6. One or more of modules 102 in FIG. 1 may also represent all or portions of one or more special-purpose computers configured to perform one or more tasks.

As illustrated in FIG. 1, exemplary system 100 may also include one or more databases, such as database 120. In one example, database 120 may be configured to store information about exploits performed through applications (e.g., including information differentiating different versions of applications).

Database 120 may represent portions of a single database or computing device or a plurality of databases or computing devices. For example, database 120 may represent a portion of server 206 in FIG. 2, computing system 510 in FIG. 5, and/or portions of exemplary network architecture 600 in FIG. 6. Alternatively, database 120 in FIG. 1 may represent one or more physically separate devices capable of being accessed by a computing device, such as server 206 in FIG. 2, computing system 510 in FIG. 5, and/or portions of exemplary network architecture 600 in FIG. 6.

Exemplary system 100 in FIG. 1 may be implemented in a variety of ways. For example, all or a portion of exemplary system 100 may represent portions of exemplary system 200 in FIG. 2. As shown in FIG. 2, system 200 may include a computing device 202 in communication with a server 206 via a network 204. Computing device 202 may be programmed with one or more of modules 102 and/or may store all or a portion of the data in database 120. Additionally or alternatively, server 206 may be programmed with one or more of modules 102 and/or may store all or a portion of the data in database 120.

In one embodiment, one or more of modules 102 from FIG. 1 may, when executed by at least one processor of computing device 202 and/or server 206, facilitate computing device 202 and/or server 206 in directing application updates. For example, and as will be described in greater detail below, one or more of modules 102 may cause computing device 202 and/or server 206 to direct application updates. For example, and as will be described in greater detail below, identification module 104 may be programmed to identify exploit information 222 that indicates a rate 230 at which installations of an earlier version 214 of an application 210 are exploited in attacks on computing system security. Identification module 104 may also be programmed to identify exploit information 224 that indicates a rate 232 at which installations of a later version 216 of application 210 are exploited in attacks on computing system security. Determination module 106 may be programmed to determine how updating application 210 from earlier version 214 to later version 216 will impact computing system security at least in part by comparing rate 230 at which installations of earlier version 214 of application 210 are exploited with rate 232 at which installations of later version 216 of application 210 are exploited. Direction module 108 may be programmed to direct at least one computing system with a determination 240 about updating an installation of earlier version 214 of application 210 (e.g., an application installation 210) to later version 216 of application 210 (e.g., an application installation 212) based at least in part on determining how updating application 210 will impact computing system security.

Computing device 202 generally represents any type or form of computing device capable of reading computer-executable instructions. Examples of computing device 202 include, without limitation, laptops, tablets, desktops, servers, cellular phones, Personal Digital Assistants (PDAs), multimedia players, embedded systems, combinations of one or more of the same, exemplary computing system 510 in FIG. 5, or any other suitable computing device.

Server 206 generally represents any type or form of computing device that is capable of collecting, storing, analyzing, and/or using information about application security. Examples of server 206 include, without limitation, application servers and database servers configured to provide various database services and/or run certain software applications.

Network 204 generally represents any medium or architecture capable of facilitating communication or data transfer. Examples of network 204 include, without limitation, an intranet, a Wide Area Network (WAN), a Local Area Network (LAN), a Personal Area Network (PAN), the Internet, Power Line Communications (PLC), a cellular network (e.g., a Global System for Mobile Communications (GSM) network), exemplary network architecture 600 in FIG. 6, or the like. Network 204 may facilitate communication or data transfer using wireless or wired connections. In one embodiment, network 204 may facilitate communication between computing device 202 and server 206.

FIG. 3 is a flow diagram of an exemplary computer-implemented method 300 for directing application updates. The steps shown in FIG. 3 may be performed by any suitable computer-executable code and/or computing system. In some embodiments, the steps shown in FIG. 3 may be performed by one or more of the components of system 100 in FIG. 1, system 200 in FIG. 2, computing system 510 in FIG. 5, and/or portions of exemplary network architecture 600 in FIG. 6.

As illustrated in FIG. 3, at step 302 one or more of the systems described herein may identify information that indicates a rate at which installations of an earlier version of an application are exploited in attacks on computing system security. For example, at step 302 identification module 104 may, as part of computing device 202 in FIG. 2, identify exploit information 222 that indicates rate 230 at which installations of earlier version 214 of application 210 are exploited in attacks on computing system security.

As used herein, the term “application” may refer to any software component capable of executing on a computing system. Accordingly, the term “application” may refer to any application, program, driver, module, service, and/or operating system that may execute on a computing system.

As used herein, the term “attack” may refer to any attempt to perform a malware installation, an exploit, an unauthorized use of computing resources, and/or an authorized access of data. As used herein, the term “exploit” may refer to any method of leveraging a security vulnerability within an application.

Identification module 104 may identify any of a variety of types of information that indicate exploit and/or attack rates connected with versions of applications. For example, identification module 104 may identify records of successful attacks and/or attempted attacks that have been directly and/or indirectly observed to involve the earlier version of the application. In this example, identification module 104 may analyze the records to determine a rate of exploits of the earlier version of the application. In some examples, identification module 104 may identify and/or determine a relative rate of exploits of the earlier version of the application (e.g., as compared to one or more later versions of the application). In some examples, identification module 104 may simply identify a rate of exploits of the earlier version of the application, a number of exploits that may be used to estimate a rate of exploits, and/or a ranking of exploit frequencies across different versions of applications that may imply a relative rate of exploits.

Identification module 104 may identify the information that indicates the rate at which installations of the earlier version of the application are exploited in any suitable manner. For example, identification module 104 may identify the information that indicates the rate by querying a security database that stores information about attacks performed on applications. For example, the security database may store data gathered from many security systems installed on many computing devices. These security systems may report to a security server when an attack (or evidence of an attack) is observed, and include in the report information about the earlier version of the application if the earlier version of the application is implicated in the observed attack. The security server may then store information about the attack in the security database for future analysis.

In some examples, identification module 104 may identify information about active exploits in the field. For example, identification module 104 may determine which exploits are currently most in use, and weigh those active exploits more heavily when determining the rate at which installations of the earlier version of the application are exploited in attacks. In some examples, identification module 104 may weigh recent reports of attacks and/or exploits more heavily than past reports.

FIG. 4 is a block diagram of an exemplary computing system 400 for directing application updates. As shown in FIG. 4, computing system 400 may include a security server 406 in communication with computing devices 420(1)-(n) that have an earlier application version 410 installed and with computing devices 420(1)-(m) that have a later application version 412 installed. Using FIG. 4 as an example, computing devices 420(1)-(n) may have reported one or more exploits of and/or attacks leveraging earlier application version 410 to security server 406. Security server 406 may have stored these reports in database 120. Accordingly, at step 302 identification module 104 may, as a part of security server 406, identify information that indicates a rate at which installations of earlier application version 410 are exploited in attacks on computing system security.

Returning to FIG. 3, at step 304 one or more of the systems described herein may identify additional information that indicates a rate at which installations of a later version of the application are exploited in attacks on computing system security. For example, at step 304 identification module 104 may, as part of computing device 202 in FIG. 2, identify exploit information 224 that indicates rate 232 at which installations of later version 216 of application 210 are exploited in attacks on computing system security.

The later version of the application may relate to the earlier version of the application in any of a variety of ways. For example, the later version of the application may represent a version of the application that immediately succeeds the earlier version of the application. Additionally or alternatively, the later version of the application may represent a version of the application to which the earlier version may be directed updated. In some examples, the later version of the application may represent any version of the application published and/or distributed at a date later than the earlier version. Additionally or alternatively, the later version of the application may represent a version of the application with a later version number than the earlier version and/or with an indicator that the later version is meant to replace the earlier version.

Identification module 104 may identify the information that indicates the rate at which installations of the later version of the application are exploited in any suitable manner. For example, identification module 104 may identify the information that indicates the rate by querying a security database that stores information about attacks performed on applications. For example, the security database may store data gathered from many security systems installed on many computing devices. These security systems may report to a security server when an attack (or evidence of an attack) is observed, and include in the report information about the earlier version of the application if the earlier version of the application is implicated in the observed attack. The security server may then store information about the attack in the security database for future analysis. In some examples, a computing device may send one or more reports to the security server when the earlier version of the application is installed, and send one or more additional reports to the security server after the application is updated to the later version.

Using FIG. 4 as an example, computing devices 422(1)-(m) may have reported one or more exploits of and/or attacks leveraging later application version 410 to security server 406. Security server 406 may have stored these reports in database 120. Accordingly, at step 304 identification module 104 may, as a part of security server 406, identify information that indicates a rate at which installations of later application version 410 are exploited in attacks on computing system security.

Returning to FIG. 3, at step 306 one or more of the systems described herein may determine how updating the application from the earlier version to the later version will impact computing system security at least in part by comparing the rate at which installations of the earlier version of the application are exploited with the rate at which installations of the later version of the application are exploited. For example, at step 306 determination module 106 may, as part of computing device 202 in FIG. 2, determine how updating application 210 from earlier version 214 to later version 216 will impact computing system security at least in part by comparing rate 230 at which installations of earlier version 214 of application 210 are exploited with rate 232 at which installations of later version 216 of application 210 are exploited.

Determination module 106 may compare the rate at which installations of the earlier version of the application are exploited with the rate at which installations of the later version of the application are exploited in any of a variety of ways. For example, determination module 106 may compare a percentage of earlier version installations that are exploited with a percentage of later version installations that are exploited and determine which percentage is higher. As another example, determination module 106 may perform a statistical analysis on the information about exploits of the earlier and later versions of the application (e.g., controlling for potentially confounding variables such as hardware configurations, computing system age, other installed applications, other vulnerability factors, etc.) to determine the relative contributions of the earlier and later versions of the application to computing system vulnerabilities.

In some examples, determination module 106 may determine that the earlier version of the application is more likely to be exploited than the later version of the application. For example, determination module 106 may determine that, after controlling for other factors, the earlier version of the application attracts and/or successfully allows more attacks than does the later version of the application. Alternatively, in some examples, determination module 106 may determine that the later version of the application is more likely to be exploited than the earlier version of the application.

At step 308, one or more of the systems described herein may direct at least one computing system with a determination about updating an installation of the earlier version of the application to the later version of the application based at least in part on determining how updating the application will impact computing system security. For example, at step 308 direction module 108 may, as part of computing device 202 in FIG. 2, direct at least one computing system with determination 240 about updating an installation of earlier version 214 of application 210 (e.g., application installation 210) to later version 216 of application 210 (e.g., application installation 212) based at least in part on determining how updating application 210 will impact computing system security.

Direction module 108 may direct the computing system with the determination in any suitable manner. For example, direction module 108 may send an instruction to a security system installed on the computing system regarding a potential update of the application. In some examples, direction module 108 may send the instruction in response to receiving a request from the computing system for information about the later version of the application. Additionally or alternatively, direction module 108 may send the instruction in response to receiving a report from the computing system that the earlier version of the application is currently installed on the computing system.

As mentioned earlier, in some examples one or more of the systems described herein may determine that the earlier version of the application is more likely to be exploited than the later version of the application. In these examples, direction module 108 may direct the computing system with any of a variety of directives to facilitate and/or encourage updating the application. For example, direction module 108 may direct the computing system to update the installation of the earlier version of the application to the later version of the application. In this example, the computing system may update the installation of the earlier version of the application to the later version in response to receiving the instruction from direction module 108. As another example, direction module 108 may direct the computing system to display a notification recommending that the installation of the earlier version of the application be updated to the later version of the application. For example, direction module 108 may classify the update as “recommended” and/or “important,” and an update manager on the computing system may present the classification to a user via a user interface. Additionally or alternatively, direction module 108 may direct the update manager to prompt a user to update the installation of the application to the later version.

In an additional example, direction module 108 may direct the computing system to disable the installation of the earlier version of the application until the installation is updated to the later version of the application. For example, direction module 108 may direct the computing system to quarantine the application and/or to disallow execution of the application until the application is updated to the later version of the application. In some examples, direction module 108 may direct the computing system to prompt a user to update the application when the user attempts to launch the earlier version of the application. Additionally or alternatively, direction module 108 may direct the computing system to sandbox the installation of the earlier version of the application. For example, direction module 108 may direct the computing system to intercept actions (such as input/output attempts, system configuration attempts) by the installation of the earlier version of the application and perform the actions on behalf of the application within one or more virtualization layers (e.g., so that, from the perspective of the application, the application can make persistent changes to the computing system, but that from the perspective of the computing system, the application can only make changes within defined boundaries, thereby preventing any attack from spreading beyond the application).

In some examples, direction module 108 may direct the computing system to not automatically update the application (or advise a user to update the application) even though the later version of the application is less vulnerable to exploits than the earlier version due to a different flaw of the later version of the application. For example, direction module 108 may determine that a stability rating of the later version of the application is lower than a stability rating of the earlier version of the application and that the application should not be updated. The stability rating may include any indication of an impact of the application on the reliability and/or performance of the computing system on which the application is installed.

As mentioned earlier, in some examples one or more of the systems described herein may determine that the later version of the application is more likely to be exploited than the earlier version of the application. In these examples, direction module 108 may direct the computing system with any of a variety of directives to prevent, protect against, and/or discourage updating the application. For example, direction module 108 may direct the computing system to not update the installation of the earlier version of the application to the later version of the application. In this example, the computing system may remove the application from a list of automatic updates to apply. Additionally or alternatively, direction module 108 may direct the computing system to block an attempt to update the installation of the earlier version of the application to the later version of the application. For example, a security system on the computing system may interfere with an attempt by an update manager to update the installation of the earlier version of the application. As another example, a security system may override a user's selection to update the installation of the application.

In an additional example, direction module 108 may direct the computing system to display a notification recommending that the installation of the earlier version of the application not be updated to the later version of the application. For example, direction module 108 may classify the update as “not recommended” and/or “dangerous,” and an update manager on the computing system may present the classification to a user via a user interface. Additionally or alternatively, direction module 108 may direct the update manager to prompt a user to avoid updating the installation of the application to the later version and/or to inform the user of the security risks of updating the installation of the application to the later version. After step 306, method 300 may terminate.

As explained above in connection with method 300 in FIG. 3, by determining whether newer versions of applications are exploited more (or less) by attacks and then directing computing systems with instructions that facilitate and/or encourage updates to more secure versions of applications and/or directing computing systems with instructions that prevent, protect against, and/or discourage updates to less secure versions of applications, the systems described herein may enhance the security of computing systems through intelligent application updating.

In one example, a security agent may collect information that includes (1) file creation information that describes who created which files on a computing system, (2) application information that identifies when an application is installed and/or updated, (3) which binaries are created as part of the application installation, (4) version information for the application, and (5) information relating to the conviction of files. A backend system may mine the above information to identify all files that created malware (e.g., in the recent past) that was subsequently detected and remediated. This backend process may also mine data to identify which application each of these files belongs to and if there is a newer version of the file available.

For each binary, the backend may then generate data that identifies information including (1) a hash of the file, (2) whether the file is actively dropping malware, (3) a name of the application that the file belongs to, (4) a version of the application that the file belongs to, (5) whether a new version of the application exists, and (6) whether the newer version is being actively exploited more than the previous version.

At any opportune time (such as during a security scan, when a user uses the application, and/or when a file is creating malware), the security agent may query the backend for file information. If the backend determines that the file is actively dropping malware and that a newer version exists (and that the newer version is not being actively exploited as much as the current version), then the security agent may take one of several actions. For example, the security agent may (1) alert and/or notify a user to update the application, (2) lock down the application until the application is updated, (3) perform the update of the application (e.g., without user input), and/or (4) virtualize all actions of the application.

In some examples, application version information may not be readily available. In these examples, one or more of the systems described herein may use heuristic methods to determine which version of an application is newer (by, e.g., relying on creation times and/or installation times of the different versions of the application across many computing systems). These systems may consider files (identified with hashes) that belong to an application and are created after files with the same file names and/or components as indicating a newer version of the application. Application stability information may also be available to the backend and may be used to recommend that users not update the application if the newer version is known to be incompatible and/or worse in terms of stability and/or user experience.

FIG. 5 is a block diagram of an exemplary computing system 510 capable of implementing one or more of the embodiments described and/or illustrated herein.
